STEAM-RADIATOR.

SPECIFICATION forming part 'of Letters Patent No. 393,287, dated November 2Ol 1888.

Application filed October G, 1887. Serial No. 951.600. (No model.)

To all whom, it may concern,.-

Be it known that I, WILLIAM J. BALDWIN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvenients in Radiators, ol which the following is a specification.

This invention relates to an improvement in radiators, as set forth in the following specilication and claims, and illustrated in the aecoinpanying drawings, in Which- Figure l represents a section along the line a' of a radiator embodying my invention. Fig. 2 is a vertical section along the line 1/ y,

Fig. l. Fig. 3 is a longitudinal section of a modification. Fig. 4 is a transverse section of Fig. 3.

In the drawings, the letter A designates a hollow easing of cast-iron or other suitable material, which easing may have the general shape of a radiator. It is provided with a steam-inlet, a, and asteam-outlet, a. In the interior of the easingare pockets B,which are preferably `formed on the longer sides ol' the casing. Said pockets may be cast directly on the sides of the casing or subsequently alllxed thereto in any manner so that they will be water-tight. These pockets B open upwardly and receive the water of condensation. Vhen steam enters the hollow easing A, the water contained in the pockets B is heated to a teniperature corresponding to that of the steam, and when the steam is turned ofi the water gives 01T its heat, imparting it to the air exte rior to the easing whereby the heat of the water of condensation is utilized and sudden changes of temperature are avoided.

An advantage of having several shallow pockets is that in case the water contained therein should freeze the casing would not be liable to fracture. Fracture of the easing is also prevented by having each pocket with a gradually increasing cross section from its bottom upward.

ln Figs. 3 and4 the casing A is shown inthe forni of a pipe or tube having a pocket, B, on cach side which extends throughout the length of the same. In ease such pipes are to be used for heating ships and the like, where they are liable to be vibrated or tilted, partitions?) may be made in the pockets B, so as to divide the same into compartments, whereby the water is less liable to fiow out of the pockets as the pipes are tilted, or the mouths of the pockets may be partly covered for the same purpose.

Vhat I claim isl. A radiatorcasing having open water pockets l, arranged one above another upon the sides of the interior of said easing and adapted to collect and retain the water oi' condensation, substantially as described.

2. A radiator-easing having water-pockets '13, arranged one above another within said casing, said pockets extending from end to end and being open at the top, substantially as described.

3. A radiator-casing having water-pockets B, arranged one above another within said casing and extending from end to end thereof, said pockets being provided with transverse partitions b atintervals and open at their tops, substantially as described.

In testimony whereof I have hereunto set my hand and seal in the presence of two sub scribing witnesses.
